Equatorial position more stable for large substituent?

Is it ALWAYS the case that when there are substituents in a cyclic molecule, the equatorial position is more stable? (Even when the substituents are right next to each other so that one would be placed down and another up towards each other?)

For all the examples this class, the equatorial position for the largest substituent is more stable.

In the molecule 1,1- bromochlorocyclohexane, we see that a Br and Cl are both attached to carbon-1. However, since Br is a bigger atom than Cl, bromine takes the equatorial position while chlorine takes the axial position.
